Air-dispersion modelling (AERMOD / CALPUFF)
Predicting what a stack's emissions will do to ground-level air quality before the plant is built — the modelling chapter every EIA needs, and the one a pollution control board actually scrutinises.

Course outline
Learn from selected clips, concept by concept
Concept 1
What a dispersion model actually predicts
Lecture 15: Introduction to Air Quality Modelling
IIT Roorkee July 2018 · English · intermediate
Why this clip: Prof. Gurjar details the basic components of an air quality dispersion model, explaining how source emissions and meteorology are used to predict pollutant concentrations at receptor locations so total concentrations can be evaluated against ambient standards.

What was rejected
12 candidates did not meet the course criteria.
- Video is in Spanish and focuses on software interface setup without explaining the physical atmospheric dispersion concepts.
- Video is in Spanish and only demonstrates software navigation in AERMET without explaining the physical principles of atmospheric dispersion.
- The video only gives a high-level flowchart summary and does not demonstrate actual terrain processing or explain how receptor spacing affects peak concentration detection.
- runs a model without any receptor discussion
- This video covers AERPLOT (a post-processor utility for generating Google Earth KMZ files) rather than setting up and running the AERMOD dispersion model.
- describes the model conceptually without running it
- describes the model conceptually without running it
- Is a software-vendor sales demonstration
- The video is in Indonesian and focuses on comparing dispersion patterns across source types rather than reading numerical concentration values against air quality standards.
- Academic conference presentation overviewing regional urban emission modeling and monitoring rather than an instructional video on reading concentrations against ambient standards.
- Is a vendor sales demonstration
- This video is a promotional overview of air dispersion modeling and does not discuss when AERMOD is the wrong model, model selection criteria, or alternative models like CALPUFF.
Where this skill is used
Environmental Planner — Pollution Control Board / EIA Cell
Environmental planning and clearance work in government — EIA review, environmental management plans, urban environment/climate cells, and regulatory compliance. Boards hire mainly environmental engineers/scientists; pure planning seats are limited to explicitly notified planning or environment-cell posts. Specialisation tag: Environmental.
